Your smartphone(智能手机) can do a lot of things. It can call people. It connects to the Internet. It enables you to play fun games. But there is a dark side to this smart little device（设备）of yours – it might also spread disease.

    “People are just as likely to get sick from their phones as from handles of the bathroom,” Jeffrey Cain, the president of the American Academy of Family Physicians, told The Wall Street Journal.

    This may be hard to believe, but scientists reached this conclusion after they tested eight random cell phones from an office in Chicago. All the tested phones showed high numbers of coliforms(大肠菌), a kind of bacteria found in excrement(粪便)，with about 2,700 to 4,200 units of the bacteria on each phone. In drinking water, the healthy limit is less than 1 unit per 100 ml of water. This bacteria can cause flu, pinkeye（红眼病）and diarrhea(腹泻).

    Although computers, keys and pens all carry germs(细菌), our smartphones get far dirtier. They touch a lot of stuff, including our hands and the inside of our pocket or purse. We take them almost everywhere: the bus, the subway and who hasn't played Angry Birds of Fruit Ninja while sitting on the toilet?

    “Some things that we think are personal are actually more public than we imagine,” Cain said.

    What's even worse is that after the phone returns from its dirty trip, it then spends most of its time cozying up to our faces. You don't think about how often you touch your phone to your face, do you? Our noses, mouths and ears are all warm and rich in grease（油脂）, an environment that germs really like.

    Compared to traditional keypads（键盘）, touch screens transmit（传播）germs more easily to hands. According to Time magazine's website, an expert in Australia warned that playing with iPads and iPhones at Apple stores is a health risk.

    So how do you keep your smartphone clean? Alcohol is effective when used to kill germs from the back and side of your phone. But it might harm the screen. There is one simple and reliable way you can reduce the germs on your phone's surface: wash your hands regularly.

    My first visit to Angkor Wat was in 1980. The country had been at war for many years and the temple was deserted and falling to pieces. Plants were growing out of the roofs, and trees were growing in the courtyards.

    Today, the temple is the scene of a busy repair programme. A team of 15 Indian experts are organizing a workforce of 400 Cambodians, most of them women, who are cleaning, repairing and rebuilding parts of this temple.

    As I walked through the courtyards, I noticed the Cambodian women devote hours to cleaning carefully a tiny area of stone. Boards are laid down to protect the precious painted stones while the repair work is going on. There are very few machines and little heavy equipment. Workers carry building materials in buckets at the end of long poles. Piles of stones lie in a corner of the courtyard, waiting to be replaced.

    The work of cleaning the stones is watched over by three Indian chemists. It is a very slow task. First they clean the stones with brushes using buckets of a weak chemical. Then gaps between the stones are filled in. Finally another material is painted onto the stones which will protect them from water forever.

Work starts every day at 7 a. m. and goes on until late afternoon six days a week, with a break at midday.

    Evening is the best time to visit the temple, after the tour groups have left. As the sun sinks lower, shadows spread across the courtyard. After sunset, the sky turns pink. The grey stone towers take on a golden colour before turning pink. Nowhere else in the world can there be such a quiet, beautiful place.

    In Chinese customs, red is the main color for weddings. It is used in different ways as it signifies love, joy and happiness. The bride's wedding gown（女礼服）is often red, the wedding invitations, gift boxes and envelopes are red and the bride and the groom's homes are decorated in red on the wedding day.

    Before the wedding, the married couples from the groom's family visit the bride's place with gifts in red baskets and boxes. One of those baskets has milk honey. Three days before the wedding, the women from the bride's family bring return﹣gifts to the groom's family.

    On the wedding day, the groom arrives at the bride's place on his way to the chapel（佛堂）. The groom has to give gifts in cash wrapped in red paper to the bride's friends for letting her go. The bride and the groom then leave for the chapel together.

    The wedding ceremony is attended only by the couple's immediate relatives. Just after the wedding ceremony, the bride serves tea to her parents in﹣laws as a tradition. The couples will then go to get wedding pictures. Then a reception（宴会）will follow.

    In the reception, a welcome speech is followed by a cake cutting ceremony. A Chinese wedding cake has many layers（层）, and each one represents a step to success for the newly married couples. So couples cut the cake from the bottom

    Public Health England (PHE) is targeting pizzas, ready meals, ready meat and takeaways. The government has also required the food industry to start using healthier food and encourage the public to opt for lower calorie foods.

    It is all part of an effort to cut calorie (卡路里) intake by 20% by 2024. The target will point to 13 different food groups, which are equal to about a fifth of the calorie taken by children. If action is not taken, PHE said, it would be prepared to ask the government to pass laws.

    PHE would be strictly monitoring progress by looking at which products people were buying and would be prepared to punish companies which do not take their duties. The government is also organizing a program encouraging adults to consume (消耗) 400 calories at breakfast and 600 each at lunch and dinner.

    At present, adults consume between 200 and 300 calories more than they should each day. PHE chief nutritionist Dr Alison Redstone said the 400-600-600 tip would make it easier for "people to make healthier choices" by being able to judge what they should be eating in each sitting.

    How many calories should we eat? It is suggested that women eat no more than 2,000 calories a day, while men should limit their intake to 2,500. For children, it depends on age. A four-year-old should consume no more than 1,300, while for teens aged 17 and 18, it is about 3,000, but overweight children are eating up to 500 calories more than that.

    Prof Russell Viner, of the Royal College of Pediatrics and Child Health, said it was a necessary move. He said, "Over the past 40 years, there had been a slow growth in food sizes, with pizzas and hamburgers simply much bigger than they were in our parents' time." The convenience of fast food at pocket money prices and the advertisement of unhealthy food and drinks to children add to the problem.

    We tend to think of our dreams as being uniquely personal­nighttime stories built from our own experiences that help us process our day-to-day lives. While dreams can give us a look into our personal selves, scientists have collected data that suggests dreams make their way into our cultural fabric(结构), showing themselves in ways that shape beliefs and expose collective anxieties.

    Roger Ivar Lohmann of Trent University conducted research with the Asabano people of the rainforest of Papua New Guinea, a unique group who didn't have outside contact until 1963. His studies looked at how dreams shape their beliefs and actions.

    According to Lohmann's research, dreams act as a sort of motivator or determinant of Asabano behavior. For instance, a dream may affect the way a person hunts or goes about treating medical conditions. The way dreams determine behavior is due to what Lohmann calls the "night residue" effect. This means that specific memories of dreams can affect the way a person acts when awake and inform their belief system.

    Dreams also seem to have an effect on the way many define themselves within their own cultures, and how sometimes reaching a distinct definition can cause anxiety.

    Matt Newsom of Washington State University spoke with college students in Berlin, and found many students had dreams surrounding conflicting views about their own identities(身份) in relation to what they saw as a return of German nationalism, which is a sensitive subject especially when we think of German identity as it's defined even many years after World War Ⅱ.

    Many students had dreams that centered around anxieties like "Where do I belong?" Many students never talked with one another about identity struggles in their dreams, yet many reported having such dreams. Newsom noted that dreams can be helpful "for identifying (识别) unspoken social and historical anxieties present in a given society."

    All of this research suggests that dreams can do more than help explain the thought of a person; we can learn about entire cultures and collective attitudes as well.

I hadn't got exercise lately and felt a bit dizzy. I was a little1 . One of my friends invited me to show up to see a2 that they said would help me feel better. Little did I know that I was about to see something I would never forget.

They introduced a young3 , Mr Patrick Henry Hughes. He was4 onto the stage in his wheelchair and began to play the piano. His fingers5 across the keys as he made beautiful music. He then began to sing as he played, and it was even more beautiful. For some reason,6 , I knew that I was seeing something special. Ten minutes later, someone came on the stage and7 a video of Patrick Henry Hughes.

Patrick was born with no eyes and a tightening of the joints which left him8 for life. Before his first birthday, he9 the piano. On his second birthday, he asked to play it. His father was10 . "We might not play baseball, but we can play music together. "

Today, Patrick is a11 at university. His father attends classes with him and he has made nearly all "A" s. He is also a trumpet player of a band. He and his father do it together — they12 all the band practices and the half-time performance in front of thousands of people.

But even more than his13 musical talent, it was Patrick's attitude to gratitude that touched me. I will never forget that night, that smile, that music, but most importantly, that14 attitude to gratitude. Gratitude can change your attitude,15 your life forever.
